One of Amazon’s $1.99 MP3 store deals today is Motown No. 1′s, Vol. 2, a comp that’s chock-full of actual Motown artists from The Supremes to Eddie Kendricks to (blech) Boyz II Men. Overall, though, it’s a pretty hot set, and certainly worth your just-under-two-dollars. Perhaps American Idol contestant Lil Rounds should pony up the cash for this one, as she named Aretha one of her favorite Motown artists during last night’s American Idol. Sigh.
